Yawning is fascinating
Besides all those weird things that people say about how a million devils go in ur mouth or how the devil sucks out ur soul if you don't cover your mouth and other things like that...
I always wondered, Why do people yawn when they see other people yawn (including me)
Well its because Your body is subconsciously empathising with that other person's tiredness- how weird is that
you don't even know them, and you feel bad for them- so you yawn! lolz
And another thing, you don't just yawn to show that you're tired
It's your body's way of tryna make you wake up, like, refreshing you i guess ( although that doesn't work for me, i still feel sleepy even after i yawn)
